Electrolyte additives for zinc-anoded secondary cells I. Brighteners, levellers and complexants

A series of potential dendrite inhibiting additives, used essentially to aid zinc electrodeposition in zinc-anoded secondary cells, has been evaluated. Their performances have been assessed by current-time techniques and typical electrodeposits have been examined both visually and by scanning electron microscopy. Of those additives examined, triethanolamine, polyvinyl alcohol, and those based on heptonate, show promise.
